Class of Service (Traffic Prioritization)
support for Windows NT 4.0 or Windows 98.
Class of Service is available only with the 3C359B NIC
NDIS 5 and NDIS 4 drivers. This feature is not available with
other 3C359B NIC drivers. Although the NDIS 5 and NDIS 4
miniport drivers are compatible with Windows 95
(version 950b, OSR2), they do not currently provide Class
of Service support for this version of Windows 95.
Class of Service (Traffic Prioritization) is an IEEE 802.5
supported feature that lets you select critical applications
for high-priority network access. Class of Service
prioritization allows stations running critical applications
under Windows NT 4.0 or Windows 98 to access network
bandwidth before other stations. The driver requests a
priority token when the selected applications transmit data.
The Class of Service feature is disabled by default; if you
want to take advantage of this feature, you must manually
enable it after installing the driver.
Before Starting Class of Service Configuration
The 3C359B NIC must be installed before you configure
Class of Service. For NIC installation instructions, see
Chapter 2, “Installing the 3C359B NIC.”
The driver must also be installed before you configure Class
of Service. For installation instructions, see the earlier
sections in this chapter.
Finally, you must also have installed the appropriate
applications that you want to prioritize through Class
of Service configuration.
